To all whom it may concern:

Be it known that I, WILLIAM R. C RTIs, a citizen of the United States, residing at Tracy City, in the county of Grundy and State of Tennessee, have invented a new and useful Lever Link, of which the following is a specification.

This invention relates to anti-skid chains used in connection I with motor vehicle wheels for increasing the traction qualities thereof.

'The primary object of the invention is to provide an anti-skid chain wherein the tread chains thereof will be automatically moved into close engagement with the tread of the tire, on which the chain is supported,

while the tire is rotating.

Another object of the'invention is to pro-v vide pivoted arms for connecting the tread chains to the supporting chains, of the de vice. i

With the foregoing and other objects i view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter clescribed and claimed, it being. understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 is a fragmental elevational view of a tire disclosing an anti-skid chain constructed in accordance with the present invention as applied thereto.

Figure 2 is a fragmental elevational view or" a tire supplied with an anti-skid chain, showing the movements of the levers whichv connect the tread chains to the lateral chains of the device.

Figure 3 is a plan View disclosing the relation of the tread chains with the tread atire.

Figure 4 is an enlarged detail view of one of the levers.

Referring to the drawing in detail, the I device embodies lateral or supporting chains 5, which are, when positioned on a 'tlre, ar-

ranged on opposite sides of the tire to support the'tread chains indicatedat 6.

as clearly shown 'ing.

These tread chains 6 are secured to the supporting chains 5 as by means of, the levers 7,;which are formed with openings 8 disposed adjacent to one ofthe ends there of,- the openings being. designed to accommodate portions of the supporting chain. 5

by Figure'3 of the draw- These levers 7; have angular portions 9,

each of which is formed with an opening 10 to accommodate the end link of the tread chains 6 associated therewith. The chain may have its ends connected in the usual and well known manner as by means of pivoted link elements, not shown. v

From the foregoing and froman observation of Figure 2 of the drawing, it will be seen that when one. ofthe tread chains 6 contactswith the ground surface, the tread chain moves in a direction opposite to the direction of rotation of the tire on which the chain is positioned, to the end that the opposite ends of the levers are rocked, moving the inner ends of the levers towards the" hub of the wheel to tighten the tread chains tread of the tire.

'6 and cause the same to closely engage the I Having thus described the invention, what- I is claimed as new is In an anti-skid chain, continuous chain supportmg sections, chain supporting levers said levers being bent intermediate their I ends, each of said levers having an openlng' formed adjacent to one end thereof to re-- ceive a tread chain of the anti-skid chain, said levers having pairs of openings to re:

ceive the continuous chain supporting sec-j tions and said continuous chain supporting sections being of lengths to loosely engage a tire and permit movement of any one lever and tread chain with respect to the adjacent leversandchains. j
